HYDROC ARBON-BURNER.

Application filed August 13, 1915.

construction in combination with a particular base having a burner jetsurrounded by air admitting jets, said burnerand air jets being inclosedwithin a frusto-conical combustion member.

Another object of the invention is to terminate the air admitting jetsat different elevations with relation to the burner jet.

\Vith the above and further objects in view, the, invention is designedto provide a hydrocarbon burner of substantial construction andsymmetrical design adapted to be installed in the various forms ofstoves and grates.

Figure 1 in the drawings illustrates the burner in front elevation. Fig.2 shows a plan view of same. front elevation of the burner showing itscomponent and primary parts in section. Figs. 4 and 5 illustrate asingle form of burner. Fig. 6 shows a plan view of one of the burnermembers with portions removed. Fig. 7 shows an end elevation of one ofthe burner members with portions removed. Fig. 8 illustrates a sectionalview of one of the burner jets.

Referring now more in particular to the drawings, wherein the same partsare des' ignated by the same reference -characters, numeral 1 designatesa pair of base members. A connecting web 2 spaces apart andsubstantially connects the said bases. The bases are provided on theirupper surfaces with annular vertical flanges 3 which form heating pans,said pans are filled with a non-combustible and fibrous material 4, suchas asbestos, which substance is adapted to absorb the surplus fuel whichmay accumulate in the heating pan at the time of first lighting same.

A plurality of air jets 5 of varying heights are integrally formed inthe base, and are adapted to furnish the necessary oxygen to supportcombustion at the burn- Specification of Letters Patent.

ers. Said jets are arranged in a cluster Within the heating pans. Theair jets are frusto-conical in form and directed toward the center ofthe pans.

A frusto-conical burner cone (3 is disposed upon each base member andsurrounds the heating pan and air jets. Said cone is pivoted to theburner member as illustrated in Fig. 7, and has its upper end providedwith a substantially large opening which promotes combustion throughwhich theflame projects.

Over each base member and above the opening of the burner cone ismounted a generating or vaporizing coil 7. Said coil is formed in thisinstance, and as illustrated, of one coil with the extremities directedin a horizontal and parallel relation above and toward the web, wherethe pipes are directed downwardly and through the central portionthereof. The extremities 8 of the coils pass through the web 2 and haveconnection with fuel feed pipe lines 9. Saidsupply lines 9 are arrangedin parallel relation and each is provided with a controlling valve 10.Beyond the connection of the controlling valve 10 the supply lines 9have common connection with a T member 11, which T-member will beconnected with a ,fuel reservoir or any suitable means of fuel supply(not.

emit. Spreaders 15 are adj ustably arranged above the burner cone andcarried by the lower portion of the coils. Said Spl'tfldt-H'S areadapted to divert the flame and spread it in an even form. The devicewill be properly installe'd in stoves or grates y arranging said deviceevenly upon the grate, due allowance being made for air to enter thebottom of the base members.

Figs. 4 and 5 show a modified form of the primary design of theinvention in the nature of a single burner, which is provir withprojections 17 which are. integraliji' formed upon the burner base. Saidproje= tions 17 are adapted to support the coil above the burner cone.The single buru r as illustrated is adapted for use in coal stoves, andin particular where a less heating capacity is required.

Fig. 7 shows the burner cone hinged back and from over the burner baseand air jets. In lighting the burners the cone will be lifted asillustrated and the source of ignition applied to the jet, or to theoil, previously introduced into the heating pans and absorbed by thesubstance contained in the pans. The flow of the fuel through the burnerjet and the amount absorbed by the porous substance is readilycontrolled through valve 10. A pair of openings 18 are provided in oneextremity of the device through which the supply lines may be directedwhere the fuel tank is more conveniently accessible through the side ofthe-stove in which the device is installed rather than from the frontwall thereof.

Among the advantages and features of this hydro-carbon burner, thehorizontal arrangement of the coils 7 is an important one. A sufficientlineal capacity of tubing is provided in said coil to admit of highefficiency in generating and vaporizing. The fuel oil will be generatedbefore it has traversed the entire length of the coil, and at this pointit will continue through the tubes and pass in contact with the walls ofsaid heated tubes and become highly superheated, which action readilycauses a further expansion of the gases forming therein and sets up asubstantially high pressure by the time the gases have traversed thecoil and passed into the burner jet. Such a feature means that the gasesemit through the burner jet under a substantial pressure and that saidgases are,

clear and dry and highly efficient in combustion.

The form and proportion of the burner cone is such as to accelerate thepassage of air, or create a strong draft through the cluster of airjets, whereby a large volume of air is introduced into the burner and aperfect combustion set up, which results in a flame of high heatingefliciency. The varying heights of the air jets is a further importantfeature in the device, in that the shorter ones project 'air at the baseof the flame and support combustion as the gas passes from the burnerjet, while the longer air jets direct a volume of air to the upperportion of the flames and there spends the air in the perfect combustionof the unburned gases which may pass upward and through the burner cone.

It is understood that changes and modifications in the form, proportionand minor details of construction may be varied without departing fromthe principles and combination herein set out and particularly pointedout in the followingclaims, to-Wit:
